Analysis of quality of life among asthmatic individuals with obesity and its relationship with pulmonary function: cross-sectional study

Influence of chronic diseases on the occurrence of depression: A 13-year follow-up study from the Survey of Health, Ageing and Retirement in Europe

The causal association between chronic diseases and depression remains unclear. This study aimed to explore the effects of types and number of chronic diseases on the risk of depression using data from the Survey of Health, Ageing and Retirement in Europe (SHARE). A self-admitted questionnaire was used to obtain data on 14 predefined chronic diseases and the European-Depression Scale (EURO-D) was used to assess depression. Among the 16,080 baseline depression-free participants aged 50+, 31.29% (5032) developed depression over 13 years. Multivariate Cox regression models showed that individuals with any chronic diseases were at higher risk of new onset depression compared to disease-free participants. The risk of new onset depression increased with an increasing number of diseases among both younger (50-64) and older (65+) adults. Individuals with heart attack, stroke, diabetes, chronic lung disease, and arthritis were at increased risk of depression across age groups. However, some age-specific associations were observed, with cancer increasing depression risk among younger- and peptic ulcer, Parkinson's disease and cataracts increasing depression risk among older adults. These findings highlight the importance of managing chronic diseases, especially among those with more than two diseases, to prevent the development of depression among middle-aged and older adults.

Correlation between levels of adipokines and inflammatory mediators with spirometric parameters in individuals with obesity and symptoms of asthma: Cross-sectional study

INTRODUCTION

The adipose tissue secretes adipokines and influences the release of inflammatory mediators contributing to a state of low-grade systemic inflammation that may change lung function.

OBJECTIVE

To correlate levels of adipokines and inflammatory mediators with lung function in individuals with obesity and bronchial asthma symptoms.

MATERIALS AND METHODS

A cross-sectional study, including women with obesity (grade II and III) with symptoms and clinical diagnosis of asthma. Anthropometric measurements (weight, height, BMI), pulmonary function test (spirometry), asthma control test questionnaire, collection of systemic inflammatory markers (blood collection) and pulmonary markers (sputum collection) were collected and were analyzed: IL-6, IL-8, TNF-α, adiponectin, resistin, leptin and C-reactive protein (CRP). The patients were stratified into two groups according to asthma control.

RESULTS

80 women were analyzed and 40% had an ACT score greater than or equal to 18 and were classified as "controlled asthma". More than half of the patients of ACT<18 score obtaining measures of FEV1, PEF and FEF25-75% below and 80% of predicted. There was a significant and negative correlation between IL-6 in the sputum with FVC and FEF25-75% in the group ACT<18 and with FVC and FEV1 in the group ACT≥18.

CONCLUSIONS

Therefore, we concluded that the increase of interleukin-6 in the sputum is related to worse pulmonary function even in patients with controlled asthma, especially in the translate airway permeability measures.

Chronic obstructive pulmonary disease as a risk factor for suicide: A systematic review and meta-analysis

BACKGROUND

Patients living with chronic obstructive pulmonary disease (COPD) commonly present several limitations in their daily activities, high depression rates, and low quality of life, which makes this population a risk group for suicide. This study aims to systematically assess the literature on the association between CPOD and the likelihood of suicide.

METHODS

The protocol was registered in PROSPERO (CRD42018096618). The Latin-American and Caribbean Health Sciences Literature (LILACS), PubMed, SciELO, Scopus, LIVIVO, Web of Science, and PsychNET databases were used as primary study sources. OpenThesis and OpenGrey were used to partially capture the "grey literature". A manual search was also performed through a systematized analysis of the references of eligible articles. The risk of bias among the studies included was assessed with the Joanna Briggs Institute Critical Appraisal Tools for Systematic Reviews. A random effects meta-analysis was performed to estimate the variation in odds ratio (OR) and 95% confidence intervals (95% CI).

RESULTS

The search provided 4762 results, from which only seven met the eligibility criteria and were ultimately included in the qualitative assessment of the review. The studies were published from 2002 to 2015. All studies presented low risk of bias. The total sample included 1390 suicide cases of COPD patients. The meta-analysis, which was based on five eligible case control studies, found that people with history of COPD are more likely to commit suicide (OR = 1.90; 95% CI = 1.27-2.48; p = 0.002).

CONCLUSION

COPD patients are 1.9 times more likely to commit suicide than people without COPD.

Nonallergic Triggers and Comorbidities in Asthma Exacerbations and Disease Severity

Asthma triggers are exogenous or endogenous factors that could worsen asthma acutely to cause an exacerbation, or perpetuate chronic symptoms and airflow limitation. Because it is well known that recent asthma exacerbations and poor symptom control are strong predictors of future disease activity, it is not surprising that the number of (allergic or nonallergic) asthma triggers in the environment correlates with the disease-related quality of life. There is a need to identify and avoid specific triggers as the centerpiece of disease management, especially in those with heightened sensitivity to certain factors.

Influence of weight loss on pulmonary function and levels of adipokines among asthmatic individuals with obesity: One-year follow-up

BACKGROUND

Individuals with obesity are more likely to develop asthma, but the exact mechanism is still uncertain and several hypotheses have been raised, such as the release of inflammatory mediators secreted by adipose tissue.

OBJECTIVE

To assess the effects of weight loss in patients submitted to bariatric surgery on pulmonary and systemic inflammation.

METHOD

The study evaluated patients undergoing bariatric surgery (Roux-en-Y gastric bypass) with the diagnosis of asthma, except smokers. The patients were evaluated at the time of entry into a preoperative weight loss group (T1), just before bariatric surgery (T2), six months after surgery (T3), and 12 months after surgery (T4). The following were measured: anthropometric data, dosage of systemic inflammatory markers by means of blood collection, pulmonary inflammatory markers obtained by induced sputum collection, pulmonary function parameters, and asthma activity assessed by a Asthma Control Test (ACT) questionnaire.

RESULTS

Nineteen patients participated in the study. There were significant reductions in the systemic levels of interleukin (IL)-8 (p = 0.002), C-reactive protein (CRP) (p = 0.003), leptin (p = 0.001) and tumor necrosis factor (TNF)-α (p = 0.007), and significant increase in the systemic levels of IL-6 (p = 0.004) over time and adiponectin in T2 (p = 0.025). In regards to pulmonary inflammation, there were significant reductions in the sputum levels of TNF-α (p < 0.001). There was no significant improvement of the pulmonary function parameters (p > 0.05) and significant improvement in asthma activity scores (p < 0.0001).

CONCLUSION

Weight loss was associated with significant changes in the systemic and pulmonary inflammatory profiles of individuals with asthma, leading to a better asthma control as a result of an increase in some anti-inflammatory mediators and a reduction of pro-inflammatory mediators.

DRAIN AMYLASE LEVELS MAY INDICATE GASTROJEJUNOSTOMY LEAKS AFTER ROUX-EN-Y GASTRIC BYPASS

BACKGROUND

Although the incidence of leaks after Roux-en-Y gastric bypass (RYGB) significantly decreased over time, their detection still remains challenging.

OBJECTIVE

This study aimed to determine the usefulness of drain amylase levels to detect leaks after RYGB.

METHODS

This is a population-based study which enrolled 170 individuals who underwent RYGB. Drain amylase levels were determined on the first and fourth postoperative days. Two thresholds were evaluated: three times higher than the serum levels (parameter I) and higher than 250 IU/L (parameter II). The main outcomes evaluated were perioperative morbidity, the occurrence of leaks, 30-day readmissions and reoperations, hospital stay, and mortality.

RESULTS

Considering the parameter I, high drain amylase levels were significantly associated with leaks (12.5% vs 0; P<0.00001). Considering the parameter II, high drain amylase levels were significantly associated with longer hospital stay (8±5.7 vs 4.5±1.3 days; P=0.00032), 30-day reoperations (50% vs 3%; P=0.000285), and leaks (50% vs 0; P<0.00001). The parameter I presented a sensitivity of 100% and specificity of 95.9%, whereas the parameter II presented a sensitivity of 100% and a specificity of 99.4%.

CONCLUSION

The determination of drain amylase levels after RYGB was a significant indicator of leaks, hospital stay, and 30-day reoperations. This finding reinforces the importance of abdominal drainage in the RYGB within this context.
